Summary: The main goal of this work was to evaluate the effects induced by mannitol- water stress in the initial growing of cotton plants. The experiment was conducted as a completely randomized design, in factorial design 4 x 5, with 3 replications. Treatments were generated by the combination of four cotton cultivars (LD CV Frego; LD CV 02; FMT 701 and IAC 25) and five levels of water stress (0; -0.3; -0.6, -0.9 and -1.2MPa), obtained with mannitol solutions. Water potentials of -0.9 MPa reduced significantly the rate of cotton plants growth. The decrease of the water potential reduced the production of dry mass of the aerial part of all cultivars and increased the production of root dry mass on -0.6MPa potential. LD CV 02 cultivar exhibited a superior performance under water stress.

O experimento foi conduzido em dezembro de 2007 em Presidente Prudente - SP. Utilizou-se o delineamento inteiramente casualizado, em esquema fatorial 4x5, com 3 repetições. Os tratamentos foram gerados da combinação de quatro 4 cultivares de algodão (LD CV Frego; LD CV 02; FMT 701 e IAC 25) e cinco níveis de deficiência hídrica (0; -0,3; -0,6, -0,9 e -1,2 MPa) obtidos a partir de soluções de manitol. Potenciais hídricos da ordem de -0,9 MPa diminuíram significativamente a taxa de crescimento das plântulas de algodão. A diminuição do potencial hídrico reduziu a produção de massa seca da parte aérea de todos os cultivares e, aumentou a produção de massa seca da raiz até o potencial de -0,6 MPa. O cultivar LD CV 02 foi o que melhor se desenvolveu sob deficiência hídrica.Revista Ciência Agronômica2010-11-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://periodicos.ufc.br/revistacienciaagronomica/article/view/84067Revista Ciência Agronômica; v. 41 n. 4 (2010)1806-66900045-6888reponame:Revista ciência agronômica (Online)instname:Universidade Federal do Ceará (UFC)instacron:UFCenghttp://periodicos.ufc.br/revistacienciaagronomica/article/view/84067/228219Echer, FábioCustódio, CeciHosomi, SilvérioDominato, JúlioNeto, Nelsoninfo:eu-repo/semantics/openAccess2023-02-28T23:52:19Zoai:periodicos.ufc:article/84067Revistahttps://periodicos.ufc.br/revistacienciaagronomicaPUBhttps://periodicos.ufc.br/revistacienciaagronomica/oai||alekdutra@ufc.br|| ccarev@ufc.br1806-66900045-6888opendoar:2023-02-28T23:52:19Revista ciência agronômica (Online) - Universidade Federal do Ceará (UFC)false
